ringfleld, in the county of Sangamon and tate dflhinoi's,

have invented a new and useful Ootton Picker, of which the followingissuch. a full, clear, and exact description as enable others skilled inthe art to make and use our said invention; A 1 r This inventionrelates, to cotton pickers purposeof the invention is to pull the fiber,by air suction, from the bolls of the-growing cotton plants'and depositit in suitable re movable receptacles carried along with the -Morespecific'purposes of the invention are to provide afan ofimprovedconstruction adapted to produce air-suction in the suction throughthefan without clogging the fan; orting on the rear part of the bed of anor inary farm wagon, the fan and an engine for provide suction-tubes ofim' ,roved construction; to provide simple an effective means forconnecting the suction-tubes with the fan and to provide means forcontrolling the operation of the suction-tubes respectively. With theseends in view our invention consists in the novel features ofconstruction and, combinations of arts shown in tlie annexe reference ishereby-Tmade and hereinafter particularly described and Referring to thedrawings in which similar reference letters and characters designatelike parts in the several views; Figure 1 is a perspective view of thecomplete apparatus in osition on a farm wagon; Figs.,2, 3, 4 and 5illustrate, on an enlarged scale, details of the head.

The flaring part of the ring K admits the cotton boll and renders thesuction most effective in detaching the fiber'fro'm the boll-.- Thedelivery pipe M is connected with the outlet ipe b of the fan, t thefree end of is a discharge-head N cona coupling m The shaped as shown inn, of greater v the outlet ipe M nected wit the pi e head N is preferaly T Fig. 3, and has an outlet opening sectionalarea than the sectionalpipe M; through charged, and a smaller orifice a "for the discharge ofdirt extracted from the cotton as A segmental concavoslots '2) convexscreen plate P ha de act the cotton arated by bars p serves to area ofthe i which the cotton is .dis

entering through the tube M and downward through the opening n; and theslots p in the plate permit the passage of dirt and its dischargetl'n'ough the orifice n. The

guides it discharge opening n being of enlarged area as described, thecotton becomes loosened as it passes downward along the plate P, andtheair pressure behind the cotton and propellmg it, expels leaves, stems,pebbles or other) dirt, through the slots p and the orifice? n.

i T1118 feature is of practical advantage because it admits of cleaningthe cotton during its passage through the head, The cotton discharged.through the head is received in sacks O or other suitable receptacleswhich may be removed at pleasure.

In the drawmgs are shown a drum equipped with four suction-tubes; thatbeing a con-= venient number to operate upon and pick the cotton fromboth sides of a central row and oneside of a row 'on each side of saidcentral row; when the wheels of thelwagon are running bctweenrowsand thewagon is passing over the central row; it is obvious however,

that'a greater or less number of suction-tubes may be used, within thescope of the invention. a

The operation of the apparatus is as fol: lows :A team hitched to thewagon pulls the Wagon across the field with the wheels travel-Operators, one for each suctiontube, carry the free ends of thesuction-tubes in their hands and walking behind the wagon apply therings K to the bolls as they are reached in succession,

, as the wagon moves slowly along the rows;

and the suction in' the tubes induced by the fan, driven by the engineA, draws the fiber from the bolls, carries it through the fan B, andthrough the delivery pipe M and the discharge head and discharges itinto the rece tacles 0. If it be desired to place one of tlicformcxtending crosswise of tubes in dis-use the pushed inward so thatthegate will lie across and close the opening of the gate-pipe com'municating with the tube;

Having fully described our invention what we claim as new and desire tosecure by Letters Patent is; i v y r 1. The combination of a wagon bed,a platthe wagon bed, bolts detachably connecting said platform withsaidwagon bed, removable receptacles within the wagon bed, a fan mountedon said platform, an nected to operatesaid 'fan, a drum connected tocommunicate with the interior of said fan,

suction tubes ,connected to communicate with said drum, an outlet pipeconnected to communicate'with the discharge opening of said fan; andadischarge head connected with said delivery pipe and adapted todiscjhargeinto the removable receptacles in the wagon bed.

2. The combination of a segmental'con cavo-convex deflector providedwith slots separated by bars; a discharge-head having a gate 9 of thegatepipe with which that tube is connected, will be engine on saidplatform condischarge opening for fiber and an orifice for 9
